Hey everyone, I really need some help on this. No matter what I do, I cannot get this to work at all.

Right now I have a NAS running a VM in which is running Microsoft Server 2016. It has an address of 10.0.0.247 and the NAS has an IP address of 10.0.0.248. 

The modem is only handing out addresses .2 - .245 and anything beyond that is statically configured. 

try to 

I installed AD and followed the setup, created the DNS server and all. The server is running it's DNS and when I do NSLOOKUP I can see the domain name on the server. Now, here's the issue. When I try to join another client into that domain in which is corpnetwork.local I get an error but when I use the NETBIOS name which is corpnetwork I get prompted for a username and password, I type in the admins info.. and it sits there spinning for about 5 minutes and says either domain doesn't exist or cannot make contact.

I did make sure that the NIC on the client is statically configured along with the Server and the NAS and the DNS of the client is set as the Servers IP so I'm directing it there. Any help to why I cannot get any computers to join the domain would be greatly appreciated.

Hi there Senbonzakura,

This is Nikolai, I can try to help you as much as I can i see there is an issue finding the domain controller, did you install DHCP on the server roles and features as well as well setting up a pool for the devices? and also after setting the DHCP server up make sure to disable the Modems DHCP address pool, do to it can interfere with the DHCP on the Windows Server VM.

I can give you this Microsoft article to help you with further instructions on how to do it  QuickStart: Install and configure DHCP Server 

Thanks and let me know if this helps any

Have a great day!

Hi,

If NETBIOS works and DNS does not, then you have a DNS issue. type "ipconfig /all" on the workstation and check a couple of items. Just below "Host name" is "Primary DNS Suffix", which in your situation should be "corpnetwork.local". If this is not so, then open the DHCP server management and check your "Server Options" and check option "015 DNS Domain Name" and set it to corpnetwork.local . Toward the bottom of the output you will see "DNS Servers" and the IP addresses of you DNS server should be displayed. If this is not so, then open the DHCP server management and check your "Server Options" and check option "006 DNS Servers" and update the entries with the correct DNS servers, which I assume is the domain controller you have already installed. Then of course on the workstation type "ipconfig /release" then "ipconfig /renew"., reboot the workstation if you feel so inclined.

From a command prompt, you should be able to type "nslookup corpnetwork.local" and it will respond with the domain name, the DNS server IP address and the IP addresses of the DNS servers if all is good with DNS from the workstation's point of view.

Cheers,
